Components

Question 1

Difference between Cell and Battery (how it looks)

Answer 1

Cell is one big line and small line, battery is a string of those

Question 2

How does a fuse look and what does it do

Answer 2

Rectangle with line going through out (Hot dog), they break if too much current flows through the circuit

Question 3

Diode how does it look and what does it do?

Answer 3

Only allows current to flow in one direction, circle with play button, an I, with a line going horizontally through it

Question 4

Ammeters, what are they, what do they look like, how are they connected

Answer 4

Ammeter is a circle with an A on it, they measure current, they’re connected in series

Question 5

Voltmeters, what are they, what do they look like, how are they added

Answer 5

Measure voltage, circle with a V on it, added in parallel

Question 6

Fixed Resistor, how does it look, what does it do

Answer 6

Box, provides a constant amount of resistance

Question 7

Variable resistor, how does it look, what does it do

Answer 7

Box with arrow diagonally going through it from bottom to top, they can modify the amount of resistance it provides

Question 8

Thermistor, what does it look like, what does it do

Answer 8

Box with crowbar going through it diagonally from top to bottom, varies its resistance depending on the temperature, if higher temp, the resistance will decrease and vice versa

Question 9

LDR, what does it look like, what does it do

Answer 9

Circle with rectangle in it, arrows coming in to top left of circle, varies resistance depending on light intensity, if light intensity increases, resistance drops and vice versa
